I just read a blog where the author is describing how arrogant God is because he is a jealous God. I notice that one issue that agnostics and atheists have in regards to christianity is perspective. They tend to look at christianity through poop colored glasses so most of what they see comes out as negative or bad. I will write a blog myself, about God's "jealousy." Maybe because I am married, and have been for over 18 years, I have a different perspective about God's jealousy.
In the blog, the author asks, "does the creator of the universe really need gnats to stroke His ego?" I don't think God's jealousy is about stroking His ego. Let me explain. I love my wife deeply. I have wonderful relationship with her and after 18 years, I don't just "love" my wife, I "enjoy" her. I truly enjoy sharing time and space with her. But I don't want to share that with anybody. I do not want another man in her life, that I have to compete with.
The Bible is filled with stories of God's people leaving His guidance to follow other "god's" and false idols. And it always gets them into trouble. When I read the Bible describe God's "jealousy" I can totally relate. God doesn't want us to love money, material things, or anything else that would cause us to put Him as second. Just like I wouldn't want another man pleasing my wife, or trying to put me in second place.
My wife and I own a gym together, so obviously I have to work with very attractive women. My wife always says "Go train her, and help her be successful but remember, you come home with me." And then she gives me her "naughty" little smile that she knows I love. That's my wires way of saying "do what you have to do, but don't go too far." That is what God is saying when he describes being "jealous." He is saying "Go ahead and go to work, make lots of money, even have nice things, but don't make any of those things more important than me."
Anyway, that's my take on the blog and my answer to my atheist friends about why I think God is a jealous God, and why I am ok with it. I'm, kind of the same way. :-)
